Be it known that'we, Lemma. slamthe county of Beltrami and State of 1nne- "sota, have invented certain new and useful Improvements in Fanning-Mills, of which,

' the'gfollowing 'isia, specification, reference. wbeingxhad to the accompanying drawings.

" This invention relates to new and'usefulimprovements in fanning millsfor separat ing grain, the object of the inventionbeing toupirovide: certain improvements whereby the operation of-cleaning. and separating certain kinds of seedsfmay be simplified and the labor connected therewith reduced to a I minimum in addition to more thoroughly cleaning and separating the seeds.

* Another-object of'tlie invention is to prowide-a fannin mill "of this character-wherein-all thelig t-seeds and foreign particles are blown from the grain before it enters into the grading. screens which will enable the mill to do more-and cleaner workthan provide a the tanning mills in use at the present time. A" further object of the invention is to fanning mill which will possess advantages in points of efiiciency anddurabilityyis inexpensiveto manufacture and atthe same time is simple in construction and operation.

With-the above and other objects i'n view,

the invention consists in the novel features I which,

of construction and the combination and arrangement. of parts hereinafter more fully described, pointed out irr the 'clai n, and shown in 'the accompanying drawings in "Figure 1 is a side elevation of a tanning mill constructed in accordance with our 1I1 rention. Fig. 2 is a top plan iew, Fig. 3

,mounted hangers 17 is the upper vibrating shoe 18, the other end of said shoe being pivotally connected to the upper end of the link bars 19, which are 'pivotally mounted upon the cross beams 8. The lower; ends ofjthe link bars 19 are pivotally connected to and adapted to supportohe end of'the grading screens'20, said grading screens being arranged in superimposed relation and shit ably secured to the side bars 21'. Pivotally secured to'one o'f the-pairsof theposts and hai ing one of their ends, pivotally connected to the outer end of the pit-man 22'a're the links 23, the inner ends of said pitman beingpiv-' otally secured to the ends of the shaft; 10. The links 23 are pivotally secured to the front end of the screens 20 by means of the pins 24 so that the screens 20 will be vibrated when motion is imparted to the gear wheel 13. each of the screens 20 and having their ends secured to each side thereof are the supporting rods Retaining plates 26 are provided; having 'one end curved upwardly as shown at are) form a. sleeve 27 which is pivotally mounted upon the rods 25 so that the body portion of the plate rests upon the screens 20 to preventflthe oats. large sticks and other foreign particles from standing on end so that the same will not pass Arranged transversely across.

through the screens 20 to the lower grading It will be understood that the grading screens 20 will be so arranged that the fine screen wireis-arranged at the bottom and the coarser screen at the top so that as the grain-passes from the screens the good grain will drop down through the finer screens on to the screen 28;, the oats, sticks and other foreign particles.v passing out at the front end of the mill as shown at 29 whilethe. good grain will be discharged to the rear of the machine-hy-means of the screen 28. The screen 28 is supported at one. end b means of the hangers 30 which are pivotally secured to the posts 2and47While the other ends of the hangers are a'djustablj andf'pivotally secured to the} reanend of the screen 28. The front end ofth'e screen .28 is'v pivot-ally links'24; 1 In separating grain byfthe .use of our i mproved tannin mill, the. thrashed grainis placed in the opper -7 and fedon to theshoe :18 by means of the adjustable feed The-grain being place board 31 said board v being adjusted by means of the crank 32 so'thatth'e' flow of grain from the hopper on to thejs'hoe' 18 will be easily controlled by the operator. An adjustable blast-reflecting board 33 is provided, the forward end of which is'ad a'pt ed to .be raised or lowered to. regulate the blast of the fan. :An adjustable end board 34 is .arranged-im-the front endof the shoe 18 and adapted. to be vertically adjusted ac cording tofthef flow of rain from the hopper.

in the hopper 7 flows from thehopper onto the shoe 18', and as it flows from 'the hopper. on to the, shoe thev blast from' thefan at therear-of the machine will separate the chafl? hulls and o'th'er lightj particles from the. grain, the-"grain passing vthrough the shoe down on. to, the grading screens Where the grain is separated fromv Y Ithe oats, sticks and other forei 11 particles Asthe grain drops from the s oe 18-fon, to thescreens 20 it will drop so as to go under.

the plates. 26 and as it moves'forward toward the front end of the'screen it passes beneath the .plates 26, the weight of the plates pre" venting the oats," sticks and other foreign:

particles, when cleaning :wheat, from rising on end by the movement of the screens. Thus it will be seen that while the grain issepa- I rated from the smallseeds' and other foreign particles, the plates 26 will not allow 'any of the foreign particles to pass through the screens 20 on to the screen28, whereas the fanning a millsjin use at the'present time .allow a great deal'of the foreign particles-to escape with the good grain, while with the use of our'improvedfanning mill, all of the a ood grain will be saved and'atthe same time will be separated. from the small seeds ."a-nd the foreign particles. The screen 28 is to be ofa fine wire mesh so that the grain will passoif the rear end of the same while the :secured to the lo' werf ends of f In a'device ofthe. character described, tlfe' small seeds and other foreignfp articles pass; th iclmgh the screens ontojthe bottdm of the .nectionl 'with the drank-iii" zit wi11,;be11 ap- Y parent that we have 'rovided a: simple and efiicient device wherehy threshe'd -grain can be uickly and'easily separated fromL-thecha and otherforeign particles, and atf'the, 50 same time will be'inexpensive ram edture.'.- While we have shown and described the I preferred form of-our'i' vention" it will be" obvious that various chah of construction and in. the i oport-ions may; .be"'resortedto forisucces'sfu 1y carryin our.

invention into practice without sacrcing.- .any of the novel features :01" departing from the scope thereof. 7 I What we claim 'is:

combination with standards, a hopper mount ed on the upper ends of said'standards, a;

. shaft'rotatably -mounted in said standards,"a reci 'roc'atory grain shoe. arranged ;beneath' sai lhopper,' fgrading screens arranged for reciprocation beneath 1 said -g1 -ain shoe,. a second reciprocatory grain shoe arranged c beneath said grading screens, a ,pitman rod;

connected at one end 'to sai'd shaft, aI-linkbar pivotally mounted intermediate of its ends on one of said standards,"o'ne end of said linkbanbeing pivotally connected tosa'id second reciprocatory grain shoe, the otherg85,

end of said link bar being pi'votall'y co'n k neotedat its extremity to the opposite end of said-pitman rod and alsopiy'otally connected at-said; other end inwardly of its ex'tremit to, said" grading screens, andfla' second'lin bar pivotally connecting said grading screen's, and-the first mentionedigrain shoe, whereby the grading screens willbe reciprocated in a cdirection-opposite-from the'-gra1n-slioes when I said shaft 1s'rotated; 1 q.
